He ended: and a kind of spell
Upon the silent listeners fell.
His solemn manner and his words
Had touched the deep, mysterious chords
That vibrate in each human breast
Alike, but not alike confessed.
The spiritual world seemed near;
And close above them, full of fear,
Its awful adumbration passed,
A luminous shadow, vague and vast.
They almost feared to look, lest there,
Embodied from the impalpable air,
They might behold the Angel stand,
Holding the sword in his right hand.

At last, but in a voice subdued,
Not to disturb their dreamy mood,
Said the Sicilian: 'While you spoke,
Telling your legend marvellous,
Suddenly in my memory woke
The thought of one, now gone from us,--
An old Abate, meek and mild,
My friend and teacher, when a child,
Who sometimes in those days of old
The legend of an Angel told,
Which ran, as I remember, thus.'

Henry Wadsworth Longfellow
